Nissan Micra Cylinder Head Exploded Diagram & Torque Specs (EM-9)
Exploded parts diagram of the cylinder head showing camshaft, valves, rocker shafts, springs and gasket with torque specifications.
This is a scanned page (EM-9) from a factory service manual, presenting an exploded-view diagram of the cylinder head assembly. The illustration identifies all major components in disassembly order, including the camshaft, camshaft retainer, camshaft oil seal, oil pump drive gear, oil pump idler gear, oil pump spring stopper and regulator spring, valve rocker cover and rocker cover gasket, cylinder head, cylinder head gasket, rocker shaft, rocker arms, rocker pivots, rocker springs, rocker shaft center retainer, valve springs and retainers, valve spring collets, valve oil seals, and the intake and exhaust valves. Torque specifications are given in N·m (kg-m, ft-lb): cylinder head bolts 64-69 N·m (6.5-7.0 kg-m, 47-51 ft-lb) with instructions to loosen in two or three steps and tighten in five steps (refer to page EM-16); rocker shaft bolts 11-15 N·m; rocker cover bolts 3-5 N·m; oil pump-related fastener 6-7 N·m; and rocker shaft-related bolts 18-21 N·m. Notes advise applying a light coat of engine oil to contact surfaces of moving parts such as the camshaft and bearings during installation, and that a punched mark on the rocker shaft shows the timing bolt side. Reference code SEM029B appears at the bottom.
